NMN Supplement
About NMN Fina Premium
Our clinic offers “NMN Fina Premium,” a supplement containing NMN (nicotinamide mononucleotide) made by Mitsubishi Corporation Life Sciences. As an inside-out approach to age-related changes in the skin and overall condition, we provide a high-quality, medical-institution-exclusive NMN supplement.
What Is NMN?
Inside the body, NMN is converted into a substance called NAD⁺ (nicotinamide adenine dinucleotide) and works as an important coenzyme deeply involved in cellular rejuvenation, including energy metabolism and DNA repair.
NAD⁺ is said to decline with age and with stress, and as a result the cells’ ability to regenerate and repair themselves also declines. There is growing interest in the possibility that supplementing NMN can support the decline in function that comes with age from the inside and contribute to aging care (health management appropriate to one’s age).
Because NAD⁺ is hard to absorb when taken directly, recent research has shown that it is more efficient to take NMN, the precursor that is converted into NAD⁺ in the body.
NMN is a substance produced in the body from vitamin B3 (niacin), a member of the B-vitamin group, and is present in the cells of all mammals. It is also contained in small amounts in foods such as broccoli, avocado, and edamame, but because it is very difficult to take in a noticeable amount through an ordinary diet, a supplement as a means of supplementation has long been awaited.
Expected Benefits of NMN
NMN is not a pharmaceutical drug, but based on current research reports and findings from human trials, the following benefits are anticipated.
- Maintaining the skin’s firmness and glow (promoting collagen production and turnover)
- Improving sleep quality and reducing daytime fatigue
- Maintaining concentration and memory
- Diet support through activation of the basal metabolism
- Support for the vague complaints that follow menopause
*The potential of NMN for hair (research stage)
In June 2025, a human clinical trial of NMN in middle-aged and older women was published through joint research by Mitsubishi Corporation Life Sciences, Waseda University, and Clinic F. In this study, a trend toward improvement in hair diameter and composition was observed after 12 weeks of NMN intake, suggesting that it may be useful for hair care. However, this was an open-label, single-arm study and does not prove the efficacy of NMN-containing products. Please note that the effect on hair is still under research.
Safety and Reliability: Made by Mitsubishi Corporation Life Sciences × Manufactured in Japan
The NMN supplement “NMN Fina” that we carry uses raw material produced by Mitsubishi Corporation Life Sciences, one of Japan’s largest manufacturers, and is made into a finished product within Japan.
- A high-quality supplement made in Japan and sold exclusively through medical institutions
- Manufacturing controlled in compliance with GMP standards
- Rigorously quality-tested for heavy metals, microorganisms, and the like
Some over-the-counter products are made overseas or of unknown purity, but this product uses only high-purity, high-quality NMN and was developed with safety as the top priority.
Easy Daily Intake by “Oral” Supplement Rather Than IV Drip
NMN is well known for IV drip therapy, but a drawback is that it requires a procedure at a medical institution and takes time and money.
Because the supplement we carry is an oral type, there is no need to visit the clinic and you can easily take it every day at home. Compared with an IV drip, we recommend it as an option superior in continuity and convenience.
Side Effects and Precautions
Research to date considers NMN a relatively safe substance, but please note the following points.
- The safety of long-term use is still under research, so those who are pregnant or breastfeeding should refrain from using it.
- Very rarely, some people report stomach discomfort or drowsiness.
- Those with a chronic illness or taking medication should consult a doctor.
Recommended For
- Those who want to incorporate aging care into daily life
- Those who want to maintain firm, clear skin
- Those who feel their sleep is light or that they tire easily
- Those interested in maintaining a healthy body
Please feel free to speak with our staff. For those who wish to purchase, we sell it after a brief consultation with a doctor.
Frequently Asked Questions (FAQ)
Q Is it okay to take the NMN supplement every day?
A
Yes, daily intake is generally recommended. Because NMN does not readily accumulate in the body, taking it continuously is expected to give stable results. However, if it does not suit your constitution or condition, please consult a doctor.
Q When is the best time to take it?
A
There is no particular rule, but taking it in the morning is said to align well with the time of day when metabolism rises. For those with a sensitive stomach, we recommend taking it after meals.
Q Is it okay to take it together with other supplements or medications?
A
Generally there is no problem, but those who are being treated for another illness or are taking medication should consult a doctor beforehand.
Q What is the difference between an NMN IV drip and the supplement?
A
An NMN IV drip is administered directly into the blood, so a fast effect can be expected, but it requires a procedure at a medical institution. The supplement, on the other hand, is easy to incorporate daily and continuously and can be easily continued at home.
Q How long does it take to feel the effects?
A
It varies from person to person, but many people feel changes such as “waking up better in the morning” or “their skin condition improving” after continuing for about one to two months.
Q I’m worried about safety; can I trust it?
A
The NMN supplement we use is made with high-purity raw material produced by Mitsubishi Corporation Life Sciences and manufactured at a GMP-certified factory in Japan. As a product for medical institutions, it undergoes strict quality control, including testing for heavy metals and microorganisms, so you can use it with confidence.
